OSHA requires that fall protection be provided when working four feet or more above a lower level. This essentially includes all walking-working surfaces (e.g., roofs, mezzanines, platforms, etc.), except:
- Portable ladders;
- Fixed ladders 24 feet or less above a lower level;
- Dangerous equipment; and
- Repair pits, service pits, and assembly pits less than 10 feet deep.
The type of fall protection required is dependent upon the fall hazard or work situation outlined in 1910.28, “Duty to have fall protection and falling object protection.”
